I take slight issue with a few things here: 1) grind settings will change for different coffees, roasts and ages (time since roast), 2) liking strong coffee and light roasts is a contradiction, the author likes dark coffee and that’s ok, 3) the 3 “waves” are not really so distinct as suggested - light roasts are not new and dark roasts are not old, and blends are favored over single origin by large coffee producers because they can be more consistent than single origin.
